Yun Ye smiled bitterly and put away the system layout, he tried not to let himself think about the experience required for the next upgrade.

He wondered angrily why this experience bar was growing so rapidly, the speed of growth was comparable to the speed of a rocket rising.

No, it should be faster than the rocket is rising.

Alas, why is it so difficult to pinch to upgrade a level?

"What do you think, little brat, if it was easy for you to get an incomparably powerful power, would you still cherish it?" The gray old man said angrily in his mind.

"You need to know that hard-won things will know how to cherish, things are like this, and so is strength. And growing your strength too fast will only be bad for you, not good! ”

Yun Ye was puzzled, why was there only a disadvantage?

Obviously, only strong strength will make it easier to live in this bloodthirsty last world.

After the gray old man noticed Yun Ye's thoughts, he just replied disdainfully, "The little kid is really a little kid." ”

Although he couldn't see the gray old man's appearance clearly, Yun Ye could also hear the gray old man's anger from that disdainful tone.

This made him smile bitterly, "Please also ask the gray old man to give the kid some guidance." ”

"Humph!" The gray old man first snorted quite arrogantly, and then said in a lazy tone

"Do you know the word hard-won?"

"Of course." Yun Ye replied with a slight puzzlement, he couldn't figure out why Gray Lao would ask like this.

"When you one day recall that your strength is all you fought out of the sea of corpses and blood, you may understand the true meaning of this sentence, in fact, this is not how stingy the system is reluctant to let you grow your strength, and the system also wants you to grow your strength quickly, so that everyone is relaxed."

"But what if you don't have enough strength to show it? So what's the use of this heavenly strength? ”

Yun Ye heard it even more foggy, why can't he give full play to his strength?

The gray old man, who sensed Yun Ye's thoughts, paused before continuing,

"If you were to go back to the rioting school now, do you think you'd still behave the same way you did back then?"

Yun Ye groaned for a while, and then came to a conclusion

It certainly won't be the same, if it were me now, the mutants in the classroom and in the corridor would only have one result.

Moreover, aside from his current strength, he used his own strength that day to deal with those two mutants, Yun Ye felt that he had no less than ten ways to easily kill them.

"Now you understand?" The gray old asked lazily.

Yun Ye's eyes lit up immediately, and then he nodded with a wry smile.

At the beginning, he knew that he could easily subdue them, but Yun Ye didn't do it because of his poor temperament.

It's also the wrist that's bad.

He was also scared at the beginning, which made his strength less than seventy percent, but after these few days of killing and fighting, Yun Ye could easily kill them with the same strength as he did when he encountered that kind of primary mutant.

At the same time, Yun Ye also understood the purpose of the Hongmeng system.

Immediately, Yun Ye made a fist salute to Gray Lao, "Thank you Gray Lao for your guidance." ”

"It doesn't seem too stupid."

“……”

Yun Ye was helpless, he found that Gray Lao was particularly interested in fighting himself for this kind of thing.

What to do when you encounter this system that likes to hit the host?

Forgive him, of course.

After all, I'm the host, so of course I have to forgive this little flaw magnanimously.

Yun Ye instantly felt that his image was incomparably tall and majestic.

When he sensed Yun Ye's inner thoughts, Gray Lao was puzzled

How can a little kid be so shameless?

……

Somewhere in Jinling City, in a heavily defended steel fortress.

A large and bright hall was filled with men in white and green uniforms, all of them with resolute faces, but they could be seen from their bloodshot pupils.

On a high platform in the hall sat several half-hundred-year-olds, their faces also wearing tiredness that could not be concealed.

An old man in a half-hundred-hundred-dressed costume spoke to the crowd below

"Thanks to the concerted efforts of all the soldiers this time, we were able to keep Jinling City, and I thank you all here."

When the people below heard this, their resolute faces fluctuated violently, but none of them spoke.

"I know that everyone is very tired at this time, but the current situation is still dangerous, there are still countless mutants outside, and there are still hundreds of thousands of dawn people in Jinling City, so the next period of time will have to work hard for the soldiers."

"It is our honor to serve our country!"

I saw that the people below suddenly spoke in unison, and the sound was deafening, echoing in the hall for a long time.

"Good! It is worthy of being my Huaxia son! ”

The half-hundred-year-old man who was speaking on the high platform laughed when he saw this, and a satisfied look appeared on his face.

"General Gao, how is the city wall being built?"

"Report to the chief, the main body of the Jinling city wall has been poured one-third in accordance with the requirements, and it is still being poured."

"Well, yes, speed things up. If necessary, you can requisition the people of the city, but you must pay them accordingly, understand? ”

"Yes!"

The people below were also overjoyed when they heard the report of the general Gao, it was a city wall dozens of meters high, and now it had been poured by a third of the city, and the speed had to be staggering.

The newly built Jinling city wall is based on the original city wall reinforcement and heightening, up to 30 meters, around the entire Jinling old city, the amount of work is huge, but once the construction is completed, it is the life line of Jinling City, and the 30-meter-high city wall is enough to resist the attack of most of the mutants.

"General Chen, how are the mutants in the city cleared?"

"Report to the chief, most of the mutants in the city have been cleared, and there are still some horns being cleaned up."

"Well, there can't be a single mutant in Jinling City, do you understand?"

"Yes!"

The half-hundred-year-old man continued to ask, "What about the casualties?" ”

The general surnamed Chen's face turned pale when he heard this, "The army suffered 5,000 wounds and sacrificed 20,000, and ordinary people suffered 3,000 injuries and 10,000 deaths." ”

The half-hundred old man frowned after hearing this, and only after half a sound did he continue to ask, "How many people have survived?" ”

"There are 132 people in the army who have survived so far, and only ordinary people have survived...... Less than thirty people. ”

Even the people who knew the probability were still breathless when they heard General Chen's reply,

Good guy, this probability is really not ordinarily low.

"yes, got it."

The old man on the high platform just nodded silently.

I saw him continue to ask aloud, "Professor Zhang, are there any new discoveries in your research institute?" ”

"......," but he replied with a moment of silence.

"Professor Zhang?" The half-hundred-year-old man was puzzled, thinking to himself, isn't that guy here?

The people below are also you look at me, I look at you, with a look of force, and a few people who know a little bit about Professor Zhang's temperament also smiled helplessly.

"Report ...... The report to the chief, the elder, the teacher, said that there is a new discovery, and it is still there, in the institute. At that moment, a young man with heavy glasses raised his hand in a winch.

Well?

All eyes were on the young man with his hand raised.

Where did the young man go through this kind of battle, he was just a small clerk doing research in the laboratory, where could he stand the killing aura of these soldiers in this hall, his legs immediately trembled, and his face was so white that he couldn't be white.

The young man looked about twenty-one or twelve years old, with thick eyes, and looked quite delicate, but his trembling little appearance looked like a little lamb that had strayed into a wolf's den.

The old man on the high platform couldn't help but shake his head when he saw the man in glasses trembling with fear.

Young people nowadays still lack exercise.

Just this breath scared him like this.

What the old man didn't know was that this hall was full of people who had experienced killing, and the killing aura exuded from his body was like a substance, they were soldiers who had experienced the baptism of war, and that young man, if it weren't for this sudden disaster, he might have stayed in the research institute for the rest of his life.

Where can they withstand such a heavy killing aura?

"What new discoveries did your teacher make?"

After hearing this, the man with glasses opened the folder in his hand in a panic, and scattered all the documents on the ground because his hands were too shaky.

Seeing this, the half-hundred-year-old man glanced at a soldier below, and the soldier immediately walked to the glasses young man with a comprehension and handed over the packed documents to the half-hundred-year-old man.

The old man opened the file and looked down line by line.

I saw that the more the old man looked at it, the more frightened he became, and his brows became deeper and deeper.

It took the old man half a long time to read it, and even though he had countless experiences, he felt that the idea in the document was too shocking.

If it succeeds, the benefits to humanity are immeasurable, and if it fails, no one can bear the consequences.

I saw him groan for a while before he said slowly.

"I've read the contents of the document, and I have to say, that guy is still as crazy as ever." The old man said with a wry smile on the corner of his mouth.

"This document mentions the idea of genetic grafting, according to his theory, if successful, the benefits for humanity will be endless, and if it fails, humanity may simply become extinct without mutants."

"...... Uproar"

Everyone below was in an uproar, the consequences of failure were so serious?

The few people who knew the identity of the old man looked at each other in surprise, is this the real strength of the people of that family?

While others were still distressed by the sudden calamity and felt overwhelmed, he was already preparing for gene grafting.

And it seems that he has achieved some success, otherwise he would not have put forward a plan that has no hope of being realized.

"This matter is very important, and I don't dare to make the decision alone, so I want to send this document to the leaders of the major military regions to decide together."

There are careful people at the bottom who noticed that the old man actually used "don't dare" instead of "can't".

This discovery shocked them even more.

Who is that old man? He is the master of this city, the leader of hundreds of thousands of troops, and there are still things in this city that he does not dare to decide?

It can be seen that what the old man said just now was by no means exaggerated in the slightest.

If this proposal succeeds, humanity will definitely benefit!

Several generals who knew Professor Zhang's temperament also shook their heads with a wry smile.

That guy is an unfathomable lunatic.

"Okay, that's it for the meeting, I have to discuss it with a few leaders right away."

After the half-hundred old man finished speaking, he left without looking back, and the pace was so fast, which showed the old man's current eagerness.
